The 302 front end utilizes the same Retainers and .0635" Tungsten Axle as the OS3 Fronts but has new brass wheels that house new tires cut to .302".  This Front End Set is only for the Aurora Tjet and similar chassis.  It is not for the TFX chassis.  The .302" tires are thinner than the wider style on the OS3 Fronts. They are not interchangeable.

Go hard into the corner and "Drop Anchor". 

OS3 302 Anchors are a weighted Front End set that maximizes the use of low center-of-gravity weight to keep the front end planted to the track reduces the tendency of the car to come out of the slot.  These utilize NEW tires that put the diameter at .302".  These tires are NOT interchangeable with the tires on the older OS3 Anchors.

The TFX Starter consist of parts to help customers with their first TFX puchase to ensure their TFX will be able to run on all tracks.  Larger tires are required for all tracks that are not as smooth as routed tracks.  This include most plastic sectional tracks where the stock low profile tires may cause the car to "Bottom Out" and fail to move correctly.  The required screws to mate the TFX to all bodies are also included along with spare guide pins. 

The set consists of larger tires (1 Pair .360" Front, 1 Pair .366" Rear and 1 Pair of .378" Rear), 1 S2-56 and 1 1-72 flat head screws, and 2 extra Black TFX Lightning Rod Guide Pins.  

These Guide Pins combine the best features of the OS3 Thunderpin and Johnny Lightning pin into one "Perfect" pin.   Lightning Rods feature a beveled hole for 1/72 screws so the pin does not have to be dug out to allow for body roll.   It also has a "Nub" on the back that press fits into the back chassis hole to lock the pin in place and prevent lateral pressure from breaking the pin free.   The nub is aided by a full size pin that fills the entire guide pin pocket.   The back of the pin is "Rough Finished" so scuffing prior to glueing is unnecessary.   The Lightning Rod will fit most chassis perfectly.   But all chassis have different size guide pin pockets.   Some chassis like the 7-9 require the pin to be slightly sanded to fit while the 6 and H chassis will have a little room around the pin.   For the popular 10-14 and A-F chassis the fit is awesome.   When inserting the pin remove all glue with an acetone or nitromethane based super glue remover to aid in fitment.   Use of Devcon Rubber Adhesive is ideal as it holds great and can be removed easily allowing quick replacement.
